This little beast of a board weighs in at just under £10 in the UK, pretty much being given away.

Take a look: http://www.st.com/jp/evalboard/product/252419.jsp

I'm wondering what use it is to the community & have been messing around getting 12 bit sines / ramps by messing around with one of the examples, but I'm flailing around in the dark really - it's a hell of a step up from writing arduino code thats for sure.

I've got a couple of toolchains up and running, coocux & atollic truestudio, and I've seen some awesome examples out there but can find little in the way of real guidance on programming it.

I just wondered if anyone else had taken a look at them with a view to adding them into the mix..

Just bought one of these for a data acquisition class that I'm taking.

$40- is a steal, but the compilers that come with the board only support 32k of ram (out of 128k).

10 years ago microcontroller dev boards less powerful would have cost
close to $1000

Try this one:

http://www.coocox.org/index.html

Supports the onboard debugger & allows use of the full board.

THanks- but it looks like this is a different board..

I'll admit the Cookie board is an arduino "format" board with a cortex bolted on, but CookieIDE isn't...next paragraph down:

"A new and highly-integrated software development environment for ARM Cortex M4, M3 and M0 based microcontrollers, which includes all the tools necessary to develop high-quality software solutions in a timely and cost effective manner."

I have to retract my statement on the compilers that came with the microcontroller. At least one of the compilers that came with the board does support the full 128k memory map.

I know I'm a bit late to this party, but it's a party that never ends...

I've been looking for a more advanced, but inexpensive platform for DSP work than a dsPIC. ST has new discovery boards, some of which contain an ARM Cortex-M7 that has DSP and FPU. I'm a bit underwhelmed by the ARMs they've chose though, but the ST website isn't very helpful IMO at finding what I want. I've also looked at Atmel ATSAMS70N20 which is an ARM Cortex-M7 with FPU and DSP (and the FPU supports both double and single precision floats). It's maximum clock speed is 300 MHz, where the best I saw from the Discovery board line was 216 MHz. However, I've not found development boards for this IC. (Note that it is the same IC used in the Tsunami Super WAV Trigger board).

I'm looking for a development board because it is tested and known to work and it would be beneficial for a synth designer to have a decent audio codec already available on the dev board.

Of course, free and useful tools would also be top of list.

Anyone out there have ideas about this?

I've got the board now. For anyone else looking to use this board (STM32F746G), it needs a USB A to mini-B cable for both power and ST-LINK (the way you program and debug the board). The cable does not come with the board, so I had to order one and now I am waiting for it. It does not have a MIDI port on the board, so I've ordered a blank shield board (from Adafruit) for Arduino Uno V3 because it has the proper spacing for pins so that it will plug directly into the Discovery board. I will solder a 6N138 to the board and connect it to the UART that is available on the Arduino Uno V3 connector. This will give me hardware MIDI input for synthesizer projects on the board.
